| IEEE8021BridgePortNumber |
uint32 |
An integer that uniquely identifies a bridge port, as
specified in 17.3.2.2 of IEEE 802.1ap.
This value is used within the spanning tree
protocol to identify this port to neighbor bridges. |
| IEEE8021BridgePortNumberOrZero |
uint32 |
An integer that uniquely identifies a bridge port, as
specified in 17.3.2.2 of IEEE 802.1ap. The value 0
means no port number, and this must be clarified in the
DESCRIPTION clause of any object defined using this
TEXTUAL-CONVENTION. |
| IEEE8021BridgePortType |
enumeration |
A port type. The possible port types are:
customerVlanPort(2) - Indicates a port is a C-tag
aware port of an enterprise VLAN aware bridge.
providerNetworkPort(3) - Indicates a port is an S-tag
aware port of a Provider Bridge or Backbone Edge
Bridge used for connections within a PBN or PBBN.
customerNetworkPort(4) - Indicates a port is an S-tag
aware port of a Provider Bridge or Backbone Edge
Bridge used for connections to the exterior of a
PBN or PBBN.
customerEdgePort(5) - Indicates a port is a C-tag
aware port of a Provider Bridge used for connections
to the exterior of a PBN or PBBN.
customerBackbonePort(6) - Indicates a port is a I-tag
aware port of a Backbone Edge Bridge's B-component.
virtualInstancePort(7) - Indicates a port is a virtual
S-tag aware port within a Backbone Edge Bridge's
I-component which is responsible for handling
S-tagged traffic for a specific backbone service
instance.
dBridgePort(8) - Indicates a port is a VLAN-unaware
member of an 802.1D bridge. |
| IEEE8021MstIdentifier |
uint32 |
In an MSTP Bridge, an MSTID, i.e., a value used to identify
a spanning tree (or MST) instance. |
| IEEE8021PbbComponentIdentifier |
uint32 |
The component identifier is used to distinguish between the
multiple virtual bridge instances within a PB or PBB. Each
virtual bridge instance is called a component. In simple
situations where there is only a single component the default
value is 1. The component is identified by a component
identifier unique within the BEB and by a MAC address unique
within the PBBN. Each component is associated with a Backbone
Edge Bridge (BEB) Configuration managed object. |
| IEEE8021PbbComponentIdentifierOrZero |
uint32 |
The component identifier is used to distinguish between the
multiple virtual bridge instances within a PB or PBB. In simple
situations where there is only a single component the default
value is 1. The component is identified by a component
identifier unique within the BEB and by a MAC address unique
within the PBBN. Each component is associated with a Backbone
Edge Bridge (BEB) Configuration managed object.
The special value '0' means 'no component identifier'. When
this TC is used as the SYNTAX of an object, that object must
specify the its exact meaning for this value. |
| IEEE8021PbbIngressEgress |
bits |
A 2 bit selector which determines if frames on this VIP may
ingress to the PBBN but not egress the PBBN, egress to the
PBBN but not ingress the PBBN, or both ingress and egress
the PBBN. |
| IEEE8021PbbServiceIdentifier |
uint32 |
The service instance identifier is used at the Customer
Backbone Port of a PBB to distinguish a service instance
(Local-SID). If the Local-SID field is supported, it is
used to perform a bidirectional 1:1 mapping between the
Backbone I-SID and the Local-SID. If the Local-SID field
is not supported, the Local-SID value is the same as the
Backbone I-SID value. |
| IEEE8021PbbServiceIdentifierOrUnassigned |
uint32 |
The service instance identifier is used at the Customer
Backbone Port of a PBB to distinguish a service instance
(Local-SID). If the Local-SID field is supported, it is
used to perform a bidirectional 1:1 mapping between the
Backbone I-SID and the Local-SID. If the Local-SID field
is not supported, the Local-SID value is the same as the
Backbone I-SID value.
The special value of 1 indicates an unassigned I-SID. |
| IEEE8021PortAcceptableFrameTypes |
enumeration |
Acceptable frame types on a port. |
| IEEE8021PriorityCodePoint |
enumeration |
Bridge ports may encode or decode the PCP value of the
frames that traverse the port. This textual convention
names the possible encoding and decoding schemes that
the port may use. The priority and drop_eligible
parameters are encoded in the Priority Code Point (PCP)
field of the VLAN tag using the Priority Code Point
Encoding Table for the Port, and they are decoded from
the PCP using the Priority Code Point Decoding Table. |
| IEEE8021PriorityValue |
uint32 |
An 802.1Q user priority value. |
| IEEE8021ServiceSelectorType |
enumeration |
A value that represents a type (and thereby the format)
of a IEEE8021ServiceSelectorValue. The value can be one of
the following:
ieeeReserved(0) Reserved for definition by IEEE 802.1
recommend to not use zero unless
absolutely needed.
vlanId(1) 12-Bit identifier as described in IEEE802.1Q.
isid(2) 20-Bit identifier as described in IEEE802.1ah.
ieeeReserved(xx) Reserved for definition by IEEE 802.1
xx values can be [3..7].
To support future extensions, the IEEE8021ServiceSelectorType
textual convention SHOULD NOT be sub-typed in object type
definitions. It MAY be sub-typed in compliance statements in
order to require only a subset of these address types for a
compliant implementation.
Implementations MUST ensure that IEEE8021ServiceSelectorType
objects and any dependent objects (e.g.,
IEEE8021ServiceSelectorValue objects) are consistent. An
inconsistentValue error MUST be generated if an attempt to
change an IEEE8021ServiceSelectorType object would, for
example, lead to an undefined IEEE8021ServiceSelectorValue value. |
| IEEE8021ServiceSelectorValue |
uint32 |
An integer that uniquely identifies a generic MAC service.
Examples of service selectors are a VLAN-ID (IEEE 802.1Q)
and an I-SID (IEEE 802.1ah).
An IEEE8021ServiceSelectorValue value is always interpreted
within the context of an IEEE8021ServiceSelectorType value.
Every usage of the IEEE8021ServiceSelectorValue textual
convention is required to specify the
IEEE8021ServiceSelectorType object that provides the context.
It is suggested that the IEEE8021ServiceSelectorType object
be logically registered before the object(s) that use the
IEEE8021ServiceSelectorValue textual convention, if they
appear in the same logical row.
The value of an IEEE8021ServiceSelectorValue object must
always be consistent with the value of the associated
IEEE8021ServiceSelectorType object. Attempts to set an
IEEE8021ServiceSelectorValue object to a value inconsistent
with the associated IEEE8021ServiceSelectorType must fail
with an inconsistentValue error.
Note that a MIB object that is defined using this
TEXTUAL-CONVENTION SHOULD clarify the
maximum value (i.e., 4094, for a VLAN ID). |
| IEEE8021ServiceSelectorValueOrNone |
uint32 |
An integer that uniquely identifies a generic MAC service,
or none. Examples of service selectors are a VLAN-ID
(IEEE 802.1Q) and an I-SID (IEEE 802.1ah).
An IEEE8021ServiceSelectorValueOrNone value is always
interpreted within the context of an
IEEE8021ServiceSelectorType value. Every usage of the
IEEE8021ServiceSelectorValueOrNone textual convention is
required to specify the IEEE8021ServiceSelectorType object
that provides the context. It is suggested that the
IEEE8021ServiceSelectorType object be logically registered
before the object(s) that use the
IEEE8021ServiceSelectorValueOrNone textual convention, if
they appear in the same logical row.
The value of an IEEE8021ServiceSelectorValueOrNone object
must always be consistent with the value of the associated
IEEE8021ServiceSelectorType object. Attempts to set an
IEEE8021ServiceSelectorValueOrNone object to a value
inconsistent with the associated
IEEE8021ServiceSelectorType must fail with an
inconsistentValue error.
The special value of zero is used to indicate that no
service selector is present or used. This can be used in
any situation where an object or a table entry MUST either
refer to a specific service, or not make a selection.
Note that a MIB object that is defined using this
TEXTUAL-CONVENTION SHOULD clarify the meaning of
'no service' (i.e., the special value 0), as well as the
maximum value (i.e., 4094, for a VLAN ID). |
| IEEE8021VlanIndex |
uint32 |
A value used to index per-VLAN tables: values of 0 and
4095 are not permitted. If the value is between 1 and
4094 inclusive, it represents an IEEE 802.1Q VLAN-ID with
global scope within a given bridged domain (see VlanId
textual convention). If the value is greater than 4095,
then it represents a VLAN with scope local to the
particular agent, i.e., one without a global VLAN-ID
assigned to it. Such VLANs are outside the scope of
IEEE 802.1Q, but it is convenient to be able to manage them
in the same way using this MIB. |
| IEEE8021VlanIndexOrWildcard |
uint32 |
A value used to index per-VLAN tables. The value 0 is not
permitted, while the value 4095 represents a 'wildcard'
value. An object whose SYNTAX is IEEE8021VlanIndexOrWildcard
must specify in its DESCRIPTION the specific meaning of the
wildcard value. If the value is between 1 and
4094 inclusive, it represents an IEEE 802.1Q VLAN-ID with
global scope within a given bridged domain (see VlanId
textual convention). If the value is greater than 4095,
then it represents a VLAN with scope local to the
particular agent, i.e., one without a global VLAN-ID
assigned to it. Such VLANs are outside the scope of
IEEE 802.1Q, but it is convenient to be able to manage them
in the same way using this MIB. |
